Question

1. The incidence angle for a light ray is 45°.
Find the value of angle of reflection.
​

Answer 1

Step-by-step explanation:

We know

/_ i = /_ r

So Angle of reflection = 45°

Answer 2

Answer:

by the law angle of incident = angle of reflection

angle of incidence is 45 deg. given

by the law mentioned above we get angle of reflection as 45deg.
